TIRE-BOLT WRENCH.

SPECIFICATION forming part of Letters Patent No. 762,049, dated June 7,1904.-

Application filed March 28, 1904:.

T0 (LZZ whom it may concern:

Be it known that I, FRANK O. GIBSON, residing at Ballston,in the countyof Alexandria and State of Virginia, have invented a new and ImprovedTire-Bolt Wrench, of which the following is a specification.

My invention relates to an improved tirebolt wrench designed to providea's imple and practical tool for quickly and conveniently removing nutsfrom bolts or applying nuts to bolts without danger to the felly and toprovide means for holding a plurality of nuts to be screwed ontoalternate bolts.

Vith other objects in View, which will be hereinafter apparent, theinvention consists in certain novel constructions and combinations sidethe telly and tire, so that the nut cannot be turned over the threads ofthe bolt. This is so by reason of the fact that there is no niche in thehead of the bolt to receive a screwdriver with which to hold the boltwhile turning off the nut, and even if there was itwould becomeobliterated or worn off by the wear of the tire. This difliculty isfurther exaggerated by the fact that the nut and bolt from constantwetting become rusted together, so as to render the starting of the nuton the bolt more difficult. The result is that in many cases the end ofthe bolt carrying the nut has to be cut off'with a cold chisel and atthe oxpense of much time and tedious labor and the scarifying of thetelly. Again, in applying. nuts to bolts in the assembling of the wheelthe same objection to turning of the bolt is present, and hence I havedesigned my invention to operate to accomplish the results desired andavoid the difliculties just enumerated.

Referring now to the accompanying drawings, Figure 1 is a perspectiveview showing my invention applied for use. Fig. 2 is a longitudinalsection thereof. Fig. 3 is a crosssoction on the line 3 3 of Fig. 2.Fig. 4 is a similar view on the line 4: 4 of Fig. 2. Fig. 5 is a detailperspective View of the nut-hold- Fig. 6 is a detail end elevation of myinvention. Fig. 7is a detail perspective view of the clutch-bardetached.

Referring now to the accompanying drawings, in which like numeralsandletters of reference indicate like parts in all the figures, 1designates a handle member, at one end of which is formed a U-shapedyoke or straddling member 2, whose free end terminates in ears 2 for thepurposes presently explained, and where the end 2? and the enlargedportion 1 of the handle member 1 join the said handle is provided with abore 1 and a slotted portion '1", as shown. The portion 1 of the handlehas shoulders 1 1 to cooperate with the shoulder 3 of the lever,fulcrumed, as at 2, with its end 3 in the slotted portion 1 of theenlarged portion 1 of thehandle, and the said portion 1 has abridge-piece 1 for the lever 3to rest on when gripped by the hand of theoperator and to hold the said lever parallel to the handle 1.

Held for longitudinal movement in the bore 1 is a clutch-bar I, having apronged' end 4: and a rack-face 4: with which face the pawl 3, fulcrumedat 5 in a cut-away portion 3 of the lever, cooperates. The bar 4 has anelongated groove 4. in its under face, in which the end 5 of theset-screw 5, held in the threaded aperture 5 of the handle 1, projectsto limit the movement of the said bar in its longitudinal direction. i

l/Velded or otherwise secured to the ears 2" of the member 2 is abearing member 6, having a flange 6 and an annular bore'6",in whichseats the annular hub 7 of the wrench 7, which includes an annular disk7 of greater diameter than that of the hub-7. its peripheral faceprovided with rack-teeth 7 for the purpose presently to appear. The hub7 is so mounted in the bore 7 that it will be free to turn on itslongitudinal axis and is provided with an annular groove 7 to The disk 7has bore 6" of the member 6.

cooperate with the end 8 of the screw-lug 8,. held in the threadedaperture 6 of the bearing member 6, the screw 7 and the lug 8 serving toprevent the head 7 leaving the bore 6".

9 designates a ratchet-arm having a handle 9 and an enlarged end 9,apertured, as at 9", to receive the flange 6 of the member 6, whereon ithas free movement in the arc of a circle perpendicular to the axial lineof the Upon the arm 9 a Y-shaped latch 10 is fulcrumed, as at 10, toallow one of its arms 10" to engage the rackteeth 7 c to cause thewrench 7 to rotate with the arm 9.

The wrench 7 has a square and tapering bore 7 e to receive the magazine11. (Shown in detail in Fig. 5, by reference to which and to Fig. 2 itwill be seen the magazine 11 is of elongated shape and adapted tocontain several nuts of one size, its outer end being formed with abridge or closure piece 11", to which the coil-spring 12 is attached,and which coil-spring 12 forces the nuts 13 toward the inner or open endof the magazine.) The sides of the magazine 11 are slitted to formspring portions 11" 11", having nibs 11 at the ends to retard or checkthe premature exit of the nuts from the magazine, but which are soarranged as to readily allow the nuts to pass out of the magazine duringthe operation of securing them to the bolt 14:. By providing differentsizes of magazines different sized nuts may be removed or secured to thebolts by simply introducing in place of the one magazine other magazinesof a different size.

From the foregoing it will be seen that when the operator desires toapply a nut to the bolt 14, passing through the whecl-felly 15 and tire16, he places the wheel in a horizontal position and adjusts theimplement, as shown in Fig. 1, with the bar 4 against the bolt-head 14:and the wrench 7 against the nut end of the felly. The parts are tightlyheld in such position by reason of the lever 3 and its pawl connectionswith the rack-face 4" of the, bar 4:. After the parts are in suchposition it is only necessary to operate the arm 9 to impart rotarymotion to the wrench 7 and screw the nut onto the bolt. To remove thenuts from the bolts, it is only necessary to reverse the direction ofrotation of the wrench 7, which is done by simply reversing the latch10, as shown in dotted lines in Fig. 6.

When used exclusively to remove nuts from the wheel, an empty magazineis preferably placed in the wrench 7, so that several nuts may bereceived thereby.

By providing the U-shaped member and the adjustable bar 4 the implementmay be used on Wheels of a variety of sizes without changing thecorrelative arrangement of the members 6 and 1, and by providing amagazine nuts of different sizes can be readily applied Having thusdescribed my invention, what I I claim, and desire to secure by LettersPatent, is-
